Review on 🌈 TULIP-33701 Fabric Paint Markers Rainbow 15 Pack: Vibrant Permanent Colors for Customizing Fabric, Wood, and Rocks by Jessica Lewis

Markers do what they promise. They are opaque enough to cover dark fabrics with a light color. I needed a white pen to draw on dark blue fabric and the first use worked pretty well. It took me a few coats to bring out the white lines, but the result was good. However, when I wanted to continue my project a week later, the marker stopped working. I kept the markers upright and even sealed the used ones with tape, but no matter how hard I tried, no matter how much I pumped, the paint wouldn't start flowing. I've even tried flipping the tip and replacing it with a different marker tip to no avail. I'm pretty sure the marker can't be empty because I only drew a small area before. That's rather disappointing.
